We cannot say when you have lost a trade in cryptocurrency trading. If you’re not careful when it comes to cryptocurrency trading, you could find yourself gambling more than you’re trading, and eventually you might lose everything you’ve invested. Never invest more money than you are willing to lose. You should consider any money you put into a trade as lost.
Ethereum'is on the trouble! Almost all the altcoins trades above the major counter-trendline but Ethereum'is not on the list anymore. It has a break downwards from the trendline and from the strong area which is not the good sign but we can find something positive also, currently, it has an opportunity to make a new higher low on the market structure and it shows ...
The second reason to buy the most liquid coins is that there are risks of scams. When you purchase Bitcoin you are sure that you will be able to sell it to somebody later. However, when you buy X coin, which is not as liquid and as popular as Bitcoin is, your risks are higher as everything depends in this case on the project, its team, goals, roadmap, background etc.

NOTE: Once you have Coinbase down, try moving onto GDAX. It’s, in overly simple terms, like a better version of Coinbase with lower fees. Coinbase operates both platforms, and both use the same logins. GDAX is the preferred exchange of many Bitcoin traders in the U.S. It caters to both pros and novices. After you master that, then consider exchanges like Bittrex and Binance.

The truth is that bitcoin is the hottest trading market right now, hotter than stock trading, oil trading, gold trading and any other market at this point. The reason people believe this is going to continue to be a hot market is because blockchain technology which is what allows transactions to happen without a central exchange. Here is another strategy on how to draw trend lines with fractals.

Embrace volatility – Cryptocurrencies are famously volatile. The price of Bitcoin, for example, went from $3,000 down to $2,000 and then leapt up to nearly $5,000, all within three months in 2017. Whilst this means risk is high, it also means the potential for profit is great too. It’s always sensible to check the volatility of the exchange you decide to go with.
Don’t FOMO. This is a spot that people most frequently lose money on. A dash of manipulation, two tablespoons of media hype, a cup of CME and CBOE announcements, and a generous handful of FOMO drove Bitcoin prices from $10,000 to $20,000 in December. Since that time, Bitcoin fell to a low of $9,000 and is currently sitting at around $11,000. It’s easy to look back and say, “if only I waited one month, then I could’ve bought at $9,000 instead of waiting for Bitcoin to hit $20,000 again for me to break even.” But the reality is, the combination of 1) being greedy, 2) investing blindly, and 3) FOMO were likely large contributors to the purchase at an all-time-high. Even in the crazy world of cryptocurrency, if a coin pumps that quickly, it will correct — it’s a matter of time. Speculative pumps are almost always followed by dips. While trying to jump onto a train going full speed sounds like something straight out of a James Bond movie, I’m sure most of us can agree we would probably save some limbs if we just waited for it at the next stop.
